' assume its natural color and quality when subjected to moisture.

In producing evaporated apples in accordance with my invention I utilize the following process:

The apples are peeled and cored and subjected to a salt solution, the salt being preferably ordinary table salt orsodiuin chlorid, the solution best adapted for the purpose being a three per cent. solution.

The apples are sliced and immediatel subjected to a bleaching agent, such as so fur fumes. If this cannot be immediately accomplished, the fruit is again subjected to a salt solution until it is convenientto subject it to the sulfur fumes. The fruit is then evaporated by subjecting it to at current of air, preferably below a temperature of 156 Fahrenheit. This is the temperature at which cooking or breaking down of Specification of Letters Iatent.

the cells begins, and is desirable to prevent the cooking action in order that the fruit when again subjected .to moisture will assume its natural quality.

By this process a product is produced in which the discoloration ordinarily found in evaporated apples is entirely avoided. The quality as to taste is very closely preserved in that the fruitcells are not broken down; in other words, the fruit is uncooked. It has been a common practice in evaporating apples to subject them to high temperature to prevent discoloration. In this process this is unnecessary. The fruit throughout the process is at no time subjected to a temperature sufiicient to cook or break down the cells. The temperature should be above 125 Fahrenheit, preferably about 145 Fahrenheit.

' W'llat I claim as new is:

1. As an article of manufacture an apple having discoloration arrested by the combined action of a salt solution and a fuming agent and in which the moisture is removed by evaporation. I

2. As an article of manufacture an uncooked apple having discoloration arrested I RALPH W. KING.
